Definitions

  • This invention relates to printing systems that imprint documents with a barcode and utilize downstream processes to track that the current number of pages in the document are present, and more particularly to such printing and tracking systems which utilize invisible ink for the barcoding.
  • Electrophotographic printing systems are known that print black barcodes during the printing of documents, and use barcode scanners in downstream processing to verify information and to check that the proper number of pages are present in the document. These systems are typically used for the printing and tracking of insurance documents, checks, manuals and other print-on-demand documents. Some customers find objectionable the appearance of visible barcodes on their documents.
  • a document printing and verification system includes a printing apparatus for printing an image on a print medium, and an inkjet printer apparatus for printing an invisible identification pattern on the print medium which is invisible to the unaided eye under natural illumination.
  • a scanner apparatus is positioned for producing an image of the identification image for verification use.
  • the scanner apparatus includes a light source for illuminating an imaging zone with light including nonvisible energy components and a camera sensitive to nonvisible light from the print medium to form an image of the nonvisible identification image.
  • the inkjet printhead is a high resolution printhead adapted to provide inkjet barcode printing resolution at least as high as 600 dots per inch. This improves the edge acuity of the barcodes, and permits very high density barcode information to be imprinted on the document page.
  • the ink used to form the invisible barcode includes a UV dye and an FR/IR dye.
  • the UV dye when illuminated with UV light provides an image of the barcode which is visible to the unaided eye, providing a visual check on the system operability.
  • the FR/IR dye is imaged using an FR/IR camera to capture electronically an image of the barcode. The captured image is then used by the controller for verification purposes.
  • Yet another aspect of the invention includes backlighting the document page with FR/IR energy, and capturing an image of the barcode with an FR/IR sensitive camera.
  • the FR/IR energy penetrates the page sufficiently to excite the FR/IR dye in the barcode ink.
  • Another aspect of the invention is a method for document printing and verification, comprising the following steps:
  • FIG. 1 An exemplary document printing and verification system 50 in accordance with the invention is shown in schematic form in FIG. 1.
  • This system includes a printer apparatus 52 positioned along the paper path 54 for printing desired text and/or graphical indicia onto the surface of a print medium 40.
  • the printer apparatus 52 can be, for example an electrophotographic printer, e.g. a laser printer, an LED printer, an inkjet printer, or any other type of printing system.
  • the printer apparatus 52 in an exemplary embodiment is a laser printer, under control of a system controller 100, which coordinates the priming of documents by the printer 52 and the verification processes performed by the barcode printer 60 and scanner 70 downstream of the electrophotographic printer 60.
  • the inkjet printer 60 Positioned downstream of the printer apparatus 52 along the paper path 54 is an inkjet printing apparatus 60 for printing a barcode on the print medium 40.
  • the inkjet printer 60 includes a high resolution, 600 dpi printhead 62 which ejects droplets 64 of invisible ink to print the barcode.
  • the printer 60 includes a carriage 64 for holding the printhead 62.
  • the printhead is connected via a fluid path to an ink reservoir 66, preferably a reservoir capable of holding a large ink volume, say on the order of 350 cc or greater.
  • inks involve a broad class of ink formulations which cannot be seen by the unaided eye when applied to a substrate and viewed with "natural” light (e.g. light from the sun) or light from conventional incandescent lamps and the like. Both of these light forms (as well as other forms which are normally used for general illumination purposes in home, businesses and like) are collectively characterized as "white” light which involves a combination of all the various colored light components which fall within a wavelength range of about 300 - 700 nm. Under these illumination conditions, the invisible ink compositions are essentially colorless. Only after illumination with other, more narrow light wavelengths do the printed images become visible or otherwise detectable (either with or without auxiliary observation equipment).
  • the printhead 62 with 600 dpi resolution is used with small spot size inks to produce smaller, denser one or two dimensional barcodes than are possible with conventional, low resolution barcode inkjet printers. These barcodes allow more data to be stored in a given printed area. By reducing the spot size, the edge acuity of the printed barcodes is increased, thereby increasing the scan reliability of the system.
  • FIG. 2A diagrammatically depicts a one-dimensional bar code 10 printed with a 300 dpi printhead, and the same one-dimensional barcode 20 but printed with a 600 dpi printhead using small spot size ink. As illustrated in FIG. 2A, the 600 dpi barcode 20 requires much less area than does the 300 dpi barcode 10.
  • the printhead 62 can also be used to print two-dimensional barcode patterns; an exemplary two-dimensional pattern is illustrated in FIG. 2B.
  • a scanner 70 is disposed along the paper path 54 downstream of the inkjet printer 60.
  • the scanner 70 includes a camera 72 for capturing an image of the barcodes on the paper passing by the camera at an imaging zone 76.
  • the imaging zone is illuminated by a first lamp 80 emitting a light beam 80A, through filter 84 and incident on the imaging zone.
  • the imaging zone is further illuminated by a second lamp 82 emitting a light beam 82A, through filter 88 and incident on the imaging zone. Light reflected from the paper is then passed through the filter 86 and to the camera 72.
  • Two illumination sources are provided in this exemplary embodiment because a single side light source tends to produce non-uniform illumination of the media being imaged by the camera. Two sources positioned on opposite sides of the media produce a more uniform illumination of the sample. Of course, for some implementations, a single side illumination source can produce acceptable results, thereby simplifying the system.
  • the ink droplets 64 emitted by the printhead 62 in this exemplary embodiment have two dyes invisible under natural light illumination.
  • One dye is a UV dye which, when illuminated by UV light of appropriate intensity, gives off a visible emission, permitting quick visual checking on the printing line to ensure the printing and verification system is working properly.
  • the second dye is a far red (“FR)/infrared (“IR”) dye which when illuminated by FR/IR energy of appropriate intensity gives off an emission which is detectable by the camera 72 to provide an image of the barcode.
  • Far red light normally involves a wavelength range of about 650 nm to 700 nm, with infrared light involving a wavelength range which exceeds about 700 nm up to about 1000 nm.
  • the FR/IR dye provides media independence and system robustness, since papers are less efficient at absorbing FR/IR wavelength energy than UV wavelength energy, resulting in stronger emissions at FR/IR.
  • the illumination sources produce light beams having significant energy in the UV and FR/IR wavelength bands.
  • the illumination sources 80, 82 are metal halide lamps to produce UV and RF/IR light components.
  • standard halogen light fixtures can be used as the illumination sources 80, 82, to produce light with FR/IR components. Because halogen lamps will not produce light energy in the UV band to excite the UV dye, a hand-held black light can be employed in this alternate embodiment to verify that the barcode printer is printing properly.
  • the lamp filters 84, 88 have a passband which matches the excitation frequency range of the FR/IR dye, and allow the use of more general lamps and cameras, i.e. lamps whose emission spectra are not limited to the specific excitation wavelengths of the FR/IR dye, and cameras having broader sensitivity than to just the FR/IR dye emission spectra.
  • One ink suitable for the purpose has an FR dye with a peak excitation frequency of 675 nanometers (nm), and an emission peak at 690 nm.
  • the camera filter 86 has a different passband from that of the lamp filters 84, 88, to keep the light energy from the illumination sources from entering the camera 72 and creating noise.
  • Suitable filters useful for the purpose of filters 84, 86 and 88 are commercially available.
  • an LS-650-F model filter from Corion, 73 Jeffery Avenue, Holliston, MA 01746, can be employed as the lamp filters 84, 88.
  • This filter has a 650 nm cutoff, and passes energy with wavelengths below 650 nm.
  • An S10-700-F model filter from Corion can be employed as filter 86.
  • This filter is a bandpass filter with its passband centered at 700 nm and with a 10 nm passband.
  • the LS-650-F filter passes sufficient IR energy at 675 nm to excite the FR dye in the ink, and the S10-700-F filter passes sufficient FR energy emitted by the dye at about 690 nm to produce good results.
  • the use of off-the-shelf filter components provides a significant cost advantage in implementing the system.
  • the camera 72 comprising the scanner 70 is sensitive to the FR/IR band of interest, and particularly in this exemplary embodiment to the FR emission band of the FR dye in the ink used to print the barcode, and so will provide an FR image of the invisible ink barcode.
  • the camera can be a CCD camera, but any camera having sensitivity in the spectral range of the FR emission from the dye can be employed.
  • the camera 72 has sensitivity to the UV emissions from the UV dye in the ink forming the identification pattern, and captures an electronic image of the identification pattern in response to the emissions from the UV dye.
  • the exemplary embodiment illustrated in FIG. 1 is particularly suited to reading two-dimensional barcodes.
  • the camera provides an image which is processed by the scanner to determine the barcode pattern.
  • Data representing the sensed barcode image is provided to the system controller 100, which determines whether the document passed under the scanner has an expected barcode.
  • the controller verifies whether all pages are accounted for.
  • the controller can generate a warning if all pages are not accounted for.
  • the final document produced by the system is verified to have all expected printed pages.
  • the barcode used in the verification procedure is invisible under natural illumination, and so does not provide an visible image which is objectionable in appearance.
  • the printer 52, printer 60 and scanner 70 can all constitute one integrated machine.
  • a document conveying system can be employed to convey documents or pages of documents as they are printed by machine 52, to the barcode printing station, and subsequently to the scanning station along the paper path. It is also contemplated that documents can be printed by one machine 52, manually carried or delivered to another printer machine 62 and subsequently manually carried to another scanner machine 70.
  • FIG. 3 An alternate embodiment of a printing and verification system in accordance with the invention is shown in FIG. 3.
  • This system 50' has the same printer 52, inkjet primer 60 and printhead 62.
  • the ink need not have the UV dye in this embodiment.
  • the illumination source 90 for the scanner 70 is placed beneath the imaging zone 76 to backlight the print media being scanned. Particularly, the print media has two opposed surfaces.
  • the barcode printer 60 prints the barcode on the first surface facing the printhead.
  • the illumination source 90 directs an illumination beam with FR/IR energy onto the second surface.
  • the longer wavelength (FR/IR) energy passes through the paper print medium well enough to excite the FR/IR dye in the ink forming the barcode printed on the top (first) side of the print medium, so that the barcode can still be imaged by the camera 72.
  • the backlighting provided by the embodiment of FIG. 3 provides several advantages.
  • a single light source 90 can be employed, and its light beam 92 can provide a more uniform illumination than a side lighting from a single light source on the same side of the print media as the camera.
  • the light source can be a laser, an LED, or the output from an optical fiber coupling a remotely located light source. Of course, a standard halogen light source could alternatively be employed.
  • Another advantage is that the camera 72 will have a view of the sample being imaged which is unobstructed by the light source. Further, the light source can be positioned very close to the back surface of the print media, effectively reducing the required output intensity of the light source.
  • Another advantage of the backlighting embodiment is that noise effects caused by glare, which can be a problem in the embodiment of FIG. 1., are eliminated.
  • FIG. 4 is a generalized schematic diagram of a further alternate embodiment of a document printing and verification system in accordance with the invention.
  • This system 50'' has the same printer 52, inkjet printer 60 and printhead 62 as described with respect to the system of FIG. 1, but uses a one-dimensional barcode scanner 70' at the scanning station.
  • the printer 60 can be simplified in this system, since it is only required to print a one-dimensional image.
  • the scanner 70' can be implemented by use of an off-the-shelf one dimensional scanner system, which includes a scanning light source 70A' and a photoreceptor 70B'.
  • One exemplary device suitable for the purpose is the Accusort model 22 uniform product code (UPC) scanner, marketed by Accusort Systems, Telford, PA 18969.
  • UPC uniform product code
  • the scanning light source of this commercial device is believed to be a laser source which emits FR energy at the excitation wavelength range of the FR/IR dye in the ink used by the printer 60, and the receptor sensitive to the FR/IR emission spectra of the dye.
  • the device 70' performs the processing of the signals from the photoreceptor to provide an output signal to the controller 100 identifying the recognized barcode.
  • the pattern printed by the printer 60 has been described as a barcode.
  • the invisible pattern can be other security or tracking indicia.
  • the image could be a document number, or provide the title of the document and/or pagination information.
  • the pattern will be referred to in a general sense as an "identification pattern.”
  • FIG. 5 is a general flow diagram illustrating in general steps of a document printing and verification method in accordance with the invention.
  • the document is printed by a document printer.
  • an invisible identification image is placed on each page of the document. This is done in an exemplary embodiment by an inkjet printer using an ink with an FR/IR dye.
  • the identification pattern printed on the document is preferably different for each page, to provide a unique identifier for each page.
  • the verification step includes verifying the presence of each page in the document. This is done in the exemplary embodiment by illuminating the document with FR/IR energy, capturing an electronic image of the identification pattern with an FR/IR camera, and using the electronic image in the verification process.
  • the document printer sequentially prints each page of the document, and the pages are sequentially sent along the paper path to the printer 60 and scanner 70.
  • the document printer can operate in a "batch" fashion wherein complete documents are printed, and the complete documents are then passed page by page through the printer 60.
  • the barcoded documents can then be assembled before the pages are scanned for verification, or alternatively sent page by page along the paper path between the printer 60 and scanner 70.
